Replace timestamp-based rsync + touch with checksum-based sync: - Use --checksum to only transfer files with actual content changes - Remove touch mechanism that caused all files to appear "newer" - Exclude .git, logs, .idea, node_modules from sync The old approach created a perpetual timestamp mismatch: 1. rsync -a preserved host timestamps 2. touch set container timestamps 3. Next build saw mismatch → transferred everything → touched again With --checksum mode: - Changed files: transferred with current time → rebuilt (correct) - Unchanged files: not transferred → keep timestamp → no rebuild (correct) Tested scenarios: - Consecutive builds: ~2 min (cached) vs ~6+ min (was full rebuild) - Modified wxWidgets file: only that file recompiled - Modified KiCad file: only that file recompiled 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> |

KiCad WebAssembly Port
Run KiCad PCBnew in the browser using WebAssembly.
Quick Start
Full Build (KiCad + All Tests)
# 1. Initialize submodules
git submodule update --init --recursive
# 2. Build KiCad WASM (Docker, ~10 min incremental, ~1-2 hours full)
./docker/build.sh
# 3. Build wxWidgets for local testing
./scripts/build-wxuniversal-wasm.sh
# 4. Build wxWidgets test apps
./scripts/build-wasm-test.sh
# 5. Run all tests
cd tests && npm install
npm test # wxWidgets tests (256 tests)
npm run test:kicad # KiCad tests (2 tests)
wxWidgets Only (No Docker)
# Requires: Emscripten SDK 4.0+, Node.js 18+
./scripts/build-wxuniversal-wasm.sh
./scripts/build-wasm-test.sh
cd tests && npm install && npm test

Two Build Workflows
1. KiCad Build (Docker)
Full KiCad PCBnew build using Docker:
# Build KiCad WASM
./docker/build.sh
# Copy output to test directory
./tests/scripts/setup-kicad-wasm.sh
# Run KiCad tests
cd tests && npm install && npm run test:kicad
Output: output/pcbnew.js, output/pcbnew.wasm
See build.md for detailed build documentation.
2. wxWidgets Test Apps (Local)
Build standalone wxWidgets test apps for feature testing:
# Build wxWidgets for WASM
./scripts/build-wxuniversal-wasm.sh
# Build test apps
./scripts/build-wasm-test.sh
# Run wxWidgets tests
cd tests && npm install && npm test
Output: tests/apps/standalone/
Prerequisites
For KiCad Build (Docker)
- Docker Desktop with 16GB+ RAM allocated
- 10+ GB disk space for build cache
For wxWidgets Build (Local)
- Emscripten SDK 4.0+
- Node.js 18+ (for tests)
# macOS
brew install emscripten node
# Initialize submodules
git submodule update --init --recursive
Testing
cd tests
npm install
# Run all tests
npm test
# Run specific tests
npm run test:kicad # KiCad tests only
npx playwright test menu # Menu tests only
See tests/README.md for test documentation.
Current Status
- wxWidgets WASM: Core widgets working (menus, dialogs, grids, trees, OpenGL)
- KiCad PCBnew: Builds and loads in browser, canvas rendering working
- In Progress: Testing wxWidgets features used by KiCad
